Social media use has grown significantly among non-profits, with 92% using Facebook, 90% using Twitter, and 70% using YouTube by 2011. While the YMCA had the fewest Facebook followers, it was the highest earning non-profit, and the Public Broadcasting Service had the most Facebook followers but was in the middle for profits. Successful social media strategies for non-profits include being aware of your brand, building conversations rather than just broadcasting, and using visual content like videos and images to tell compelling stories. Non-profits use social media primarily to gain supporters, raise funds, and gather volunteers.
